Abstract The evidence for the existence of cosmic rays with energies in excess of 1020 eV is now overwhelming. There is so far no indication of the GZK cutoff in the energy spectrum at 5 × 1019 eV. This conclusion is not firm for lack of statistics. A cutoff would be expected if the sources of the cosmic rays were distributed uniformly throughout the

Ultra High Energy Cosmic Rays (UHECRs) represent the most energetic source of elementary particles available to scientists. They have macroscopic energies, exceeding 5 × 1019 eV, and as yet unidentified sources. Unfortunately, their flux is as low as one particle per century per square kilometre, requiring dedicated detectors with huge apertures to ...

The interpretation of observations on cosmic rays above 1015 eV is discussed in simple terms, without considering detailed models. The variation of the amplitude of anisotropy with energy (compared with a “leaky box” picture) and the anisotropy in galactic latitude (indicating a local density gradient) strongly suggest a galactic origin for particles ...
